CIF is a declarative modeling language for the specification of discrete event, timed, and hybrid systems as a collection of synchronizing automata. The CIF tooling supports the entire development process of controllers, including among others specification, supervisory controller synthesis, simulation-based validation and visualization, verification, real-time testing, and code generation. Combined they enable a synthesis-based engineering approach to efficiently and cost-effectively design and implement high-quality controllers.

CIF is one of the tools of the Eclipse ESCET™ project. Visit the project website for downloads, installation instructions, source code, general tool usage information, information on how to contribute, and more.
